user@ubuntu:~$ sudo nano /path/to/the/fileYou can change the default settings for nano by editing its configuration file. For example, to stop nano from wrapping text simply make the following changes to /etc/nanorc:
## Don't wrap text at all.
set nowrapConsider the implications of enabling the root account, and then proceed with:
user@ubuntu:~$ sudo passwd rootTo disable the root account again, use the following command:
user@ubuntu:~$ sudo passwd -l rootChange the default permissions for your installation by editing the value for umask in /etc/profiles and /etc/login.defs.
